okay so i was listening to spotify free on my pc with my playlist going while doing homework when it stopped playing music so i clicked into the program and it was paused. i pressed play then when it stopped a few seconds into the song again i noticed the 'cant play current track' banner up the top. the song was I'm Not A Vampire by Falling in Reverse. i decided just to skip it but then another FiR song didnt work so i tested all my songs. they were all fine but 4 out of 6 of the FiR songs i had added. i cant get them to work again and it is literally just that band not working. any help?
